Abstract:
The similarity coefficient methods are more flexible in incorporating manufacturing data into the machine cells formation process in group technology. When threshold value is applied it is impossible to consider the restriction of number of cells or pact family. This paper discusses how a function is defined on Similarity coefficients and generates a threshold value which specifies an upper band on number of cells.
